The tank seal member 206 is an example of an annular seal member disposed between the tank connection portion 214 and the body connection portion 112. The annular seal member may be disposed on the tank connection portion 214 side or on the main body connection portion 112 side.

The main body portion 100 has a main body protruding tube portion 150. The main body protruding pipe portion 150 constitutes a flow path extending from the water conduit portion 102. The main body protruding tube portion 150 has an inner flow passage 152. The inner flow path 152 forms a first water flow R1 (described later). The main body protruding tube portion 150 protrudes upward. The upper end of the main body protruding tube portion 150 is located below the upper end surface 140 of the main body connecting portion 112. The main body protruding tube portion 150 has an upper end opening 154. The upper end opening 154 is an upper end of the inner flow path 152. The main body protruding tube portion 150 has a seal member 156. The seal member 156 is an annular seal member. The sealing member 156 is an O-ring. The seal member 156 connects the main body projecting tube portion 150 and the inflow passage forming portion 268 in a watertight manner. A continuous flow path is formed from the main flow path 110 of the water guide 102 to the inflow hole 240 by this connection. The water flowing out of the outflow hole 250 does not flow into the continuous flow path.

The main body protruding tube portion 150 enters the tank protruding tube portion 264 (see fig. 7). The upper end of the main body projecting pipe portion 150 is located above the lower end of the tank projecting pipe portion 264. The main body protruding tube portion 150 overlaps the tank protruding tube portion 264, so that a double-walled tube portion DP1 is formed.

Fig. 9 is a perspective view of the water flow branch member 300, fig. 9 (b) and 9 (c) are plan views of the water flow branch member 300, and fig. 9 (d) is a side view of the water flow branch member 300. In fig. 9 (b) and 9 (c), the phases of the water flow branching members 300 are different.

The water flow branching member 300 has an upper flow passage forming portion 302, a lower flow passage forming portion 304, a branching opening 306, a partition wall 308, and an upper opening 310. The upper flow channel forming section 302 and the lower flow channel forming section 304 form flow channels inside of them. The flow path formed by the water flow branching member 300 is interrupted between the upper flow path forming portion 302 and the lower flow path forming portion 304. The interrupted portion is a branch opening 306. The branch openings 306 are separated by a partition wall 308. A plurality of (three) partition walls 308 are provided. The branch opening 306 is partitioned into a plurality of (three) openings 306a by the partition walls 308 (see fig. 9 (b) and 9 (c)).

The water flowing through the flow path of the lower flow path forming portion 304 located on the downstream side reaches the branch opening 306. A part of the water flow flows into the flow path of the upper flow path forming portion 302. The other water flows out from the branch opening 306 to the outside of the water flow branch member 300. Thus, the water flow branching member 300 functions to branch the water flow.

In the main body part 100, the water flow branch member 300 forms a main body protruding tube part 150. The upper flow passage forming portion 302 forms the main body projecting pipe portion 150. The upper opening 310 is the upper opening 154 previously described.

The water flowing out of the branch opening 306 flows into the branch flow path 130 (see fig. 7). The water flowing out from the branch opening 306 flows into the water outlet 104 without passing through the medicine-containing case 200. The water flowing into the upper flow path forming portion 302 flows out from the upper opening 310 (upper end opening 154) toward the medicine storage case 200.

By rotating the water flow branching member 300, the amount of branched water flowing out from the branched opening 306 to the branched flow path 130 can be adjusted. In the phase of fig. 9 (b), the two openings 306a face the branch flow path 130 side. Therefore, the amount of branched water increases. In the phase of fig. 9 (c), one opening 306a faces the branch flow path 130 side. Therefore, the amount of branched water is reduced as compared with the phase of (b) of fig. 9. When the amount of the branched water increases, the amount of water reaching the medicine storage space 230 decreases, and the duration of the medicine becomes longer. When the amount of branched water decreases, the amount of water reaching the medicine storage space 230 increases, and the duration of the medicine becomes shorter. With the water flow branching means 300, the duration of the medicament can be adjusted.

The water flow branching member 300 forms a water flow branching portion 320, and the water flow branching portion 320 branches a part of the water flow from the main flow path 110 to the branch flow path 130. In the present embodiment, the water flow branching portion 320 is formed by the water flow branching member 300 as a separate member, but is not limited to this embodiment. The water flow branching part 320 may be formed of a member integrated with the other part.

Fig. 10 is a conceptual diagram illustrating the flow of water in the shower head 10. The water flows downstream in the main channel 110 and reaches the water flow branching portion 320 (water flow branching member 300). In the water flow branching member 300, a part of the water flows as a branched water flow flowing out from the branch opening 306, and reaches the water outlet portion 104 through the branch flow path 130. This flow is also referred to as a second water flow R2. The water flow that is not branched flows through the main body projecting tube portion 150 and the inflow channel 272, and flows into the medicine storage space 230 from the inflow hole 240. The water flowing into the drug storage space 230 flows out of the outflow hole 250 while eluting the drug, and reaches the spout 104 from the branch flow channel 130. This flow is also referred to as first water flow R1.

As shown in fig. 10, in a state where no medicine is disposed, water flowing out of the inflow hole 240 becomes water spray. The water spray reaches the upper surface 232c of the medicine storage space 230. The water pressure of the water passage connected to the shower head 10 is usually about 0.25 to 0.3 MPa. When the water pressure is supplied as the running water pressure to the shower head 10, the water flowing out of the inflow hole 240 reaches the upper surface 232c as the water jet. Under a running water pressure of 0.2MPa or more, the water flowing out of the inflow hole 240 reaches the upper surface 232c as a jet water. That is, when the hydrodynamic pressure is 0.2MPa or more, water from the holes of the inflow hole 240 forms water spray reaching the upper surface 232 c. Under this running water pressure, the water spray from the inflow hole 240 reaches the upper surface 232c regardless of the posture of the shower head 10. Under this running water pressure, the water jet from inflow hole 240 reaches upper surface 232c in the posture of shower head 10 in which the center line of inflow hole 240 is vertical. Under this running water pressure, in the shower head 10 in the reference state, the water spray from the inflow hole 240 reaches the upper surface 232 c. In the case where the sectional area D1 of the inflow opening can be adjusted, it is preferable that the water spray from the inflow opening reaches the upper surface 232c regardless of the sectional area D1. In the case where the ratio (D1/D2) of the cross-sectional area D1 of the inflow hole to the cross-sectional area D2 of the outflow hole can be adjusted, it is preferable that the water spray from the inflow hole reaches the upper surface 232c regardless of the ratio (D1/D2). When the flow rate ratio of the first water flow R1 to the second water flow R2 can be adjusted as in the second embodiment described later, it is preferable that the water jet from the inflow hole reaches the upper surface 232c regardless of the flow rate ratio. The dynamic water pressure is supplied to the shower head 10, and is measured at the water inlet (hose connection portion 106) of the shower head 10.

Fig. 11 shows the first water flow R1 immediately after the medicine 700 is disposed. In this embodiment, the medicament 700 is cylindrical. In this embodiment, the medicament 700 is a carbonated tablet. Fig. 11 shows a state immediately after the drug 700 is disposed, and elution of the drug 700 is not performed. The water flowing in from the inlet hole 240 contacts the bottom surface of the medicine 700, flows through the bottom surface 232a of the medicine housing space 230 while eluting the medicine 700, and flows out from the outlet hole 250.

Fig. 12 shows the first water flow R1 in a state where the elution of the drug 700 has progressed halfway. The elution of the drug 700 proceeds gradually at the position where the drug contacts the water jet from the inflow hole 240. The water spray slowly erodes the medicament 700. The water spray digs holes in the medicament 700. Eventually, the water sprays through the medicament 700. The through-hole 702 is formed by spraying water. Fig. 12 shows the first water flow R1 at the beginning when the through-hole 702 is formed. When the through hole 702 is formed, the water spray from the inflow hole 240 contacts the upper surface 232 c. Most of the water contacting the upper surface 232c flows along the side surface 232b to the bottom surface 232a to be discharged from the outflow hole 250.

The shower head 10 has the following effects.

The medicine storage case 200 is detachable from the main body 100. Therefore, the replacement of the medicine 700 is easy. Further, the medicine housing case 200 can be attached by merely pushing it to the main body 100 and rotating it, and the medicine housing case 200 can be detached by merely pulling it out by rotating it in the reverse direction. The medicine storage case 200 can be easily attached and detached.

The medicine storage box 200 is detachable and replaceable. By replacing the medicine-containing case 200 with a different type, the performance of the shower head 10 can be changed. For example, the shower head 10 may have the first medicine housing 200 and the second medicine housing 200 which are different from each other in the sectional area of the inflow hole 240. By replacing the medicine-containing case 200, the duration can be easily changed.

A continuous flow path is formed from the main flow path 110 of the water guide 102 to the inflow hole 240. Therefore, the water pressure reaches the inflow hole 240 and flows into the medicine storage space 230. In addition, the continuous flow path helps to eject water from the inflow hole 240. In the above embodiment, the inflow channel forming portion 268 is connected to the main body protruding tube portion 150 in a watertight manner, thereby forming the continuous channel. Even when the watertight connection is not provided, a continuous flow path is formed by providing the double-walled pipe portion DP2 by overlapping the main body projecting pipe portion 150 with the inflow flow path forming portion 268. Even if there is no overlap, a continuous flow path is formed by the watertight connection of the inflow flow path forming portion 268 and the main body protruding tube portion 150. The water flowing out of the outflow hole 250 does not enter the continuous flow path.

The inflow hole 240 is disposed only on the center side of the bottom surface 232a with respect to the outflow hole 250. Therefore, the water flowing out of the inlet 240 easily contacts the center of the medicine 700, and a through hole 702 (see fig. 12) is easily formed in the medicine 700. After the through-hole 702 is formed, the first water flow R1 flowing from the upper surface 232c along the side surface 232b and discharged from the outlet 250 is easily formed. In the case where the opening of the inflow hole 240 includes the center point of the bottom surface 232a, the flow is easily formed. The case where only one inflow hole 240 is provided facilitates the water spouting from the inflow hole 240 and the formation of the first water flow R1. Reducing the cross-sectional area D1 of the inflow opening 240 also helps to eject water from the inflow opening 240 and form the first water flow R1.

The first water flow R1 causes the portion of the medicine 700 that contacts water to sequentially change from the bottom surface of the medicine 700 to the center of the medicine 700 and further to the side surface of the medicine 700. Therefore, the drug 700 is not dissolved out with one breath, and a desired duration can be obtained. In addition, since the water flows along the housing inner surface 232, the housing inner surface 232 is washed. Thus, the residue, trash, and the like of the medicine 700 are removed. In addition, when the wall portion forming the medicine storage space 230 has transparency, visibility of the inside is improved by washing, and the state of the medicine 700 is easily checked.

The bottom surface 232a is formed with a projection 234, and the medicine 700 is disposed on the projection 234 (a high level surface h 1). Water can flow on the low level surface h2, and water can be smoothly discharged from the outflow hole 250. The generation of water accumulation in the medicine storage space 230 can be suppressed, and a desired duration can be obtained.

Water from the inflow holes 240 forms a spray of water to the upper surface 232 c. Thus, the above-mentioned water flow is formed. The water jet reaching the upper surface 232c is formed when the dynamic water pressure is 0.2MPa or more, and therefore the water flow can be obtained in a normal use state connected to the water supply line.

In the shower head 10, a first water flow R1 and a second water flow R2 (see fig. 10) are formed, the first water flow R1 reaches the water outlet portion 104 from the main flow path 110 through the inflow hole 240, the medicine housing space 230, and the outflow hole 250, and the second water flow R2 reaches the water outlet portion 104 from the main flow path 110 without passing through the medicine housing space 230. By thus branching off the flow, the water output can be ensured and the desired duration can be achieved.

The tank connecting portion 214 has a tank projecting pipe portion 264 projecting downward, and the main body portion 100 has a main body projecting pipe portion 150 projecting upward, and the main body projecting pipe portion 150 forms a flow path toward the inflow port 240. The tank connection portion 214 overlaps the main body projecting pipe portion 150, and forms a double-walled pipe portion DP1 (see fig. 7). Therefore, a continuous flow path can be formed from the main flow path 110 of the water guide 102 to the inflow hole 240. Water flowing out of the outflow hole 250 does not enter the continuous flow path. Therefore, the above-described first water flow R1 is effectively realized. In addition, a structure in which the medicine housing case 200 can be easily attached and detached is realized.

The tank connecting portion 214 has an inflow channel forming portion 268. The inflow channel forming portion 268 is open at the lower side. The lower end of the inflow channel forming portion 268 is open. The inflow channel forming section 268 forms an inflow channel 272 from below to the inflow hole. The main body projecting tube portion 150 is inserted into the inflow channel forming portion 268. Therefore, a double-walled pipe portion DP2 (see fig. 7) is formed in which the main body projecting pipe portion 150 overlaps the inflow channel forming portion 268. Therefore, the flow path from the main flow path 110 of the water guide 102 to the inflow hole 240 is continuous, and a desired duration can be obtained.

In the present embodiment, the main body projecting tube portion 150 is inserted into the inner flow path forming portion 268, but the inner flow path forming portion 268 may be inserted into the main body projecting tube portion 150 in reverse. In this case, the double-walled pipe portion DP2 is formed so that the main body projecting pipe portion 150 overlaps the inflow channel forming portion 268.

Further, the inflow flow path forming portion 268 is water-tightly connected with the main body protruding tube portion 150. Therefore, the continuity of the flow path from the main flow path 110 of the water guide 102 to the inflow hole 240 is further improved, and a desired duration can be obtained.

By pressing the medicine-containing case 200 against the main body 100 and rotating, the case connection portion 214 of the medicine-containing case 200 and the main body connection portion 112 are connected watertight. Therefore, the medicine housing box 200 can be easily attached. The tank connection portion 214 is inserted into the body connection portion 112, and the annular seal member 206 is disposed between the tank connection portion 214 and the body connection portion 112. Therefore, the attachment and detachment of the medicine housing case 200 are easy, and watertight connection is achieved. The connection structure between the main body 100 and the medicine storage case 200 may be an insertion structure that is realized only by pressing as in the above-described embodiment, or may be a screw connection or the like.

The medicine storage case 200 is detachably attached to the main body 100 of the shower head 10. The medicine-containing case 200 has a case projecting tube 264 projecting downward. Therefore, the structure is easily attachable to and detachable from the main body 100. Further, a structure in which the double-walled pipe portion DP1 is easily formed between the medicine storage case 200 and the main body portion 100 is realized. The inflow hole 240 and the outflow hole 250 communicate with the inside of the tank projecting pipe portion 264, and thus a structure that is easily attachable to and detachable from the main body portion 100 is realized.

A water flow dividing portion 274 (see fig. 6 (b)) is provided inside the case protruding tube portion 264, and the water flow dividing portion 274 divides an inflow flow path through which water entering the inflow hole 240 flows and a flow path through which water flowing out of the outflow hole 250 flows. Therefore, the distinction of the inflow hole 240 and the outflow hole 250 becomes clear. An inflow passage through which water entering the inflow hole 240 passes is formed inside the water flow dividing portion 274, and a passage through which water flowing out of the outflow hole 250 passes is formed between the water flow dividing portion 274 and a wall portion forming the case protruding tube portion 264. Therefore, the inflow hole 240 can be disposed on the center side of the bottom surface 232a with respect to the outflow hole 250.

The medicine-containing case 200 is composed of a case main body 202 and a lid 204. The tank main body 202 includes a tank opening 210 that opens the drug storage space 230 upward, and a tank connection portion 214. The cover 204 closes the tank opening 210. With this configuration, the medicine 700 can be easily disposed in the medicine housing space 230.

The cross-sectional area D1 of the inlet 240 is preferably 0.5mm from the viewpoint of obtaining the discharge amount of water flowing out of the inlet 240²The aboveMore preferably 0.6mm²Above, more preferably 0.7mm²The above. The sectional area D1 is preferably 15mm from the viewpoint of obtaining the ejection height of the water flowing out of the inflow hole 240²Hereinafter, more preferably 14mm²Hereinafter, more preferably 13mm²The following. In the above embodiment, the inflow hole 240 is a circular hole, and the cross-sectional area D1 is the area of the circle calculated from the hole diameter. When there are a plurality of inflow holes, the total of the cross-sectional areas of these inflow holes is the cross-sectional area D1. The cross-sectional area D1 may also be the area of the opening at the bottom surface 232 a.

When the medicine 700 is a gas-generating medicine such as a carbonated tablet, if the cross-sectional area D2 of the outflow hole 250 is small, the internal pressure of the medicine housing space 230 increases, and the inflow of water from the inflow hole 240 is blocked. From this viewpoint, the cross-sectional area D2 of the outflow hole 250 is preferably 20mm²Above, more preferably 25mm²Above, more preferably 30mm²The above. From the viewpoint of suppressing the restriction of the design of the wall thickness by the drug-containing case, the cross-sectional area D2 is preferably 45mm²Hereinafter, more preferably 40mm²Hereinafter, more preferably 35mm²The following. In addition, as in the above-described embodiment, when there are a plurality of outflow holes 250, the total of the cross-sectional areas of these outflow holes 250 is the cross-sectional area D2. In the above embodiment, the sectional area D2 is the area of the outflow hole 250 in the plan view of the bottom surface 232a (fig. 5 (b)).

By optimizing the ratio (D1/D2), the inflow from the inflow holes 240 and the outflow from the outflow holes 250 are thereby appropriately adjusted to obtain a desired duration. The ratio (D1/D2) is preferably 0.005 or more, more preferably 0.01 or more, and still more preferably 0.02 or more. The ratio (D1/D2) is preferably 0.50 or less, more preferably 0.45 or less, and still more preferably 0.40 or less.

The inner diameter of the medicine-housing case 200 is indicated by a double-headed arrow D3 in fig. 7. Since commercially available carbonic acid tablets sometimes swell, the inner diameter D3 is preferably larger than the outer diameter of the carbonic acid tablet. Considering a pharmaceutical preparation (carbonic acid tablet) having an outer diameter of 27mm, the inner diameter D3 is preferably 29mm or more, more preferably 30mm or more, and still more preferably 31mm or more. If the inner diameter D3 is too large, the medicine 700 moves greatly in the medicine storage space 230, and thus the variation in the duration becomes large. From this viewpoint, the inner diameter D3 is preferably 45mm or less, more preferably 40mm or less, and still more preferably 35mm or less.

The method and duration of dissolution of the carbonated tablets was verified using the shower head 10. Two medicine containers 200 having different inlet holes 240 in diameter are prepared, and the shower heads of embodiments 1 and 2 are obtained by replacing them. In example 1, the diameter of the inflow opening 240 was set to 1mm (the cross-sectional area D1 was 0.785 mm)²) The sectional area D2 of the outflow hole 250 was set to 32.052mm². In example 2, the diameter of the inflow hole 240 was set to 4mm (the cross-sectional area D1 was 12.6 mm)²) The sectional area D2 of the outflow hole 250 was set to 32.052mm²。

The shower head 10 was connected to the water supply line (water pressure 0.2MPa), and water was discharged actually with the water temperature set at 40 ℃. First, in example 1 and example 2, shower discharge was performed in a state where the medicine storage space 230 was empty. In either embodiment, the water is branched into two streams as shown in fig. 10, and the water jet flowing out of the inflow hole 240 reaches the upper surface 232c and flows along the receiving inner surface 232. The water spray from the inflow hole 240 reaches the upper surface 232c regardless of the posture of the shower head 10. Next, when the carbonic acid tablet 700 having an outer diameter of 27mm was put into the medicine storage case of example 1 and water was discharged, it was confirmed that the portion where the carbonic acid tablet 700 was dissolved was changed in order to the bottom surface, the center portion, and the side surface, and the through hole 702 was formed. When it was confirmed that the same carbonic acid tablet 700 was put into the medicine-housing case of example 2, the portion where the carbonic acid tablet 700 melted was changed in order to the bottom surface, the center portion, and the side surface, and the through-hole 702 was formed. The transparency of the medicine-containing case 200 allows the flow of water and the dissolved state of the carbonic acid tablet in the medicine-containing case 200 to be confirmed from the outside. The duration of example 1 was 5 minutes and the duration of example 2 was 2 minutes. In this way, it was confirmed that the duration can be changed only by replacing the medicine-containing case 200.

The medicine 700 is disposed in the medicine housing space 230. The medicine 700 has a size and a shape capable of being accommodated in the medicine accommodating space 230. A typical medicament 700 is a tablet (troche).

The medicament 700 is not limited. Preferably, the medicament 700 is a solid. The medicament 700 dissolves in water and acts on the effluent. Examples of the components contained in the drug 700 include sodium sulfate, sodium chloride, sodium borate carbonate, potassium carbonate, hyaluronic acid, L-ascorbic acid, citric acid, and sodium hydrogen carbonate. The preparation 700 may also contain crude drugs, seaweed extract, etc. In this embodiment, the medicament 700 is a carbonated tablet. The carbonic acid tablet reacts with water to generate carbonic acid gas.

Fig. 13 (a) is a plan view of a tank main body 402 as a modification of the tank main body 202, fig. 13 (B) is a cross-sectional view taken along the line B-B in fig. 13 (a), and fig. 13 (C) is a cross-sectional view taken along the line C-C in fig. 13 (a). Fig. 14 (a) is also a plan view of the tank body 402, fig. 14 (B) is a sectional view taken along the line B-B in fig. 14 (a), and fig. 14 (C) is a sectional view taken along the line C-C in fig. 14 (a). The position of the moving member 404 differs between (a) to (c) of fig. 13 and (a) to (c) of fig. 14. In fig. 13 (a) to (c), the moving member 404 is located at the first position. In fig. 14 (a) to (c), the moving member 404 is located at the second position.

The tank body 402 includes a moving member 404, a slide groove 406, an inflow hole 408, and an outflow hole 410. The moving member 404 has a slide engaging portion 404a and a through hole 404 b. The slide engagement portion 404a is a stepped portion formed on the outer peripheral surface of the moving member 404. The slide groove 406 is interrupted at a portion where the outflow hole 410 is formed (see fig. 14 (b)), but the distance of the interruption is short enough not to hinder the movement of the moving member 404 from the first position to the second position. The slide engaging portion 404a and the slide groove 406 constitute a slide mechanism for moving the moving member 404. During the movement of the moving member 404, the slide engaging portion 404a slides in the slide groove 406.

As shown in fig. 13 (a) to (c), the moving member 404 located at the first position completely covers the inflow hole 408. However, since the through hole 404b communicates with the inflow hole 408, water flows into the medicine housing space from the through hole 404 b. In this case, the cross-sectional area of the inflow hole is the cross-sectional area of the through hole 404 b. The cross-sectional area is smaller than the cross-sectional area of inflow opening 408.

As shown in fig. 14 (a) to (c), the moving member 404 located at the second position is completely displaced from the inflow hole 408. In this case, inflow hole 408 is fully functional. In this case, the cross-sectional area of the inflow hole is the cross-sectional area of the inflow hole 408.

When the moving member 404 is positioned intermediate the first position and the second position, the moving member 404 can partially cover the inflow hole 408. In this case, the cross-sectional area of the inflow hole can be gradually changed according to the position of the moving member 404.

In this way, the medicine storage case of the case main body 402 has an adjustment mechanism capable of adjusting the cross-sectional area of the inflow hole. The medicine storage case of the case main body 402 has an adjustment mechanism capable of adjusting the ratio (D1/D2) of the cross-sectional area D1 of the inflow hole to the cross-sectional area D2 of the outflow hole. The adjustment mechanism is implemented by a moving member 404 that can move to a position covering the inflow hole 408 and a position not covering the inflow hole 408.

The box main body 402 has a projection 412 that engages with the moving member 404 located at the second position. As shown in fig. 14 (b) and (c), the protrusion 412 engages with the through hole 404 b. The protrusion 412 helps to retain the moving member 404 in the second position.

The moving member 404 can be simply moved by, for example, a finger. The moving member 404 is easy to move without a cap and a medicine.

Fig. 15 is a perspective view of the shower head 20 of the second embodiment as viewed from the back side. The shower head 20 is identical to the shower head 10 except for having a rotating mechanism capable of rotating the water flow branching member from the outside. The shower head 20 has a medicine storage case 200 and a main body 500.

Fig. 16 (a) is a plan view of the body 500 as viewed from above. The main body 500 has a water flow branching member 600.

Fig. 17 (a) is a perspective view of the water flow branching member 600, and fig. 17 (b) is a plan view of the water flow branching member 600.

The water flow branching member 600 has the same structure as the water flow branching member 300 described above. The water flow branching member 600 has an upper flow passage forming portion 602, a lower flow passage forming portion 604, a branching opening 606, a partition wall 608, and an upper opening 610. The upper flow channel forming section 602 and the lower flow channel forming section 604 form a flow channel inside of them. These flow paths constitute a part of the main flow path.

As shown in fig. 21 (c), the box body portion 902 has a lid seal arrangement portion 918. The cap seal arrangement 918 is a circumferential groove. Although not shown in fig. 21 (a) to (d), a cap seal member 920 is disposed in the cap seal disposition portion 918 (see fig. 18 and 19). The cap sealing member 920 is an O-ring. The cover sealing member 920 seals between the box body portion 902 and the cover portion 904.

As shown in fig. 21 (c), the case body 902 (the medicine housing case 900) has a connection seal arrangement portion 922. The connecting seal arrangement 922 is a groove along the circumference. The tank connecting portion 914 has a tank sealing member 906. Although not shown in fig. 21 (a) to (d), the tank seal member 906 (see fig. 18 and 19) is disposed in the connection seal disposition portion 922.

The box main body 902 has a side wall 924. The side wall portion 924 is a cylindrical wall portion. The side wall portion 924 is a wall portion that forms the side surface 932b of the housing inner surface 932. The upper side of the side wall portion 924 is open, forming a tank opening 910.

The box body portion 902 has transparency. The case body 902 is made of a transparent resin. By virtue of this transparency, the medicine 700 contained in the medicine containing box 900 is visually recognized from the outside.

The medicine storing case 900 has a case connecting portion 914 and a medicine storing space 930. The tank connecting portion 914 is provided below the medicine storage space 930.

The medicine housing case 900 has a housing inner surface 932. The receiving inner surface 932 defines a medicine receiving space 930. The housing inner surface 932 faces the medicine housing space 930. The receiving inner surface 932 has a bottom surface 932a, a side surface 932b, and an upper surface 932 c. The bottom surface 932a has a protrusion 934. The protruding portion 934 protrudes upward. Due to the projection 934, a part of the bottom surface 932a becomes high. The bottom surface 932a has a high level h1 and a low level h 2. The high level h1 is the upper surface of the projection 934. The low level h2 is at a lower level than the high level h 1. The side surface 932b is formed by the side wall 924. The side surface 932b is the inner surface 924b of the sidewall portion 924. The upper surface 932c is formed by the cover 904. The upper surface 932c is the inner surface 904b of the cover 904.

The medicine housing case 900 has a flow hole 940. The flow hole 940 is only one. The flow hole 940 is the only opening formed in the receiving inner surface 932. A plurality of flow holes 940 may also be provided. The flow holes 940 are open at the bottom surface 932 a. The flow hole 940 is opened at the low level h 2. The flow hole 940 allows water to flow into the medicine storage space 930 and allows water in the medicine storage space 930 to flow out.

The medicament 700 is carried on the projection 934. The medicine 700 is placed on the high level h 1. The medicine 700 is floated from the low level h 2. The flow hole 940 is opened at the low level h 2. Since the medicine 700 floats from the low level surface h2, water easily flows on the bottom surface 932 a. In particular, the outflow of water from the flow holes 940 becomes smooth. This facilitates the formation of the second water stream R2. Further, since the medicine 700 floats from the low level surface h2, excessive elution of the medicine 700 due to retention of water can be suppressed, and a desired duration can be obtained.

In the combination of the medicine housing case 900 and the medicine 700, the medicine 700 has a shape and a size of the medicine housing space 930 housed in the medicine housing case 900. The medicine 700 is preferably disposed in the medicine storage space 930 in a state of abutting against the high level surface h1 and floating from the low level surface h 2.

The opening of the flow hole 940 includes the center point of the bottom surface 932 a. That is, the center point of the bottom surface 932a is located inside the flow hole 940 in a plan view. In the present embodiment, the center point of the bottom surface 932a is the center point of the flow hole 940 in a plan view.

As shown in fig. 19, the tank connecting portion 914 constituting the lower portion of the medicine storage tank 900 includes an outer peripheral surface 958, a lower end opening 960, a connecting hollow portion 962 extending upward from the lower end opening 960, and a lower end surface 963. A lower end opening 960 is formed at the lower end of the medicine housing case 900. The connection cavity 962 is open at the lower side. The lower end surface 963 is also a lower end surface of the medicine housing case 900. The tank connecting portion 914 has a tank projecting tube portion 964. The tank projecting pipe portion 964 projects toward the lower side. The lower end opening 960, the connection hollow portion 962, and the lower end surface 963 are constituted by a case protruding tube portion 964. The inner peripheral surface 966 of the case projecting pipe portion 964 defines a connection hollow portion 962. The outer peripheral surface 958 of the case protrusion tube portion 964 is provided with the aforementioned engaging portion 916.

The flow hole 940 communicates with the inside of the tank projecting pipe portion 964. The flow hole 940 communicates with the connecting cavity 962. Water flows into the medicine storage space 930 from the flow hole 940 through the connecting cavity 962. The water flows out from the flow hole 940 to the connecting cavity 962 and flows toward the water outlet 804. The connecting cavity 962 forms an inflow/outflow channel through which water flowing into the flow hole 940 and water flowing out of the flow hole 940 pass. In the medicine storage case 800, water flowing into the medicine storage space 930 and water flowing out of the medicine storage space 930 are not separated.

As shown in fig. 19 and 20, the body connecting portion 812 has an upper end surface 840 and an insertion support portion 842. The case connection portion 914 of the medicine accommodating case 900 is inserted into the main body connection portion 812. The insertion support portion 842 constitutes an inner surface of the body connecting portion 812. The insertion support 842 has a circumferential inner surface 844 and a body snap 846. The circumferential inner surface 844 has a sealing abutment surface 848. The insertion support portion 842 supports the tank connecting portion 814 inserted into the body connecting portion 812. The circumferential inner surface 844 supports an outer peripheral surface 958 of the tank connecting portion 914. The main body engagement portion 846 has: a vertical slot 846a that is open on the upper side and extends in the insertion direction (up-down direction); and a lateral slot 846b, the lateral slot 846b being connected to and extending circumferentially from a lower end of the longitudinal slot 846 a. The body engaging portion 846 engages with the engaging portion 916 of the tank connecting portion 914. When the medicine storage case 900 is pressed toward the main body connection part 812, the engaging part 916 is slidably inserted into the vertical groove 846 a. Then, by rotating the medicine storage case 900, the engaging portion 916 enters the lateral groove 846b and reaches the end of the lateral groove 846 b. By this pressing and rotation, the attachment of the medicine housing box 900 to the main body 800 is completed. In contrast, the medicine storage case 900 is removed, and the medicine storage case 900 is rotated and pulled out. The mounting and dismounting of the medicine housing case 900 is easy.

The seal abutment surface 848 of the body connecting portion 812 abuts against the box seal member 906 (see fig. 18). By this contact, the medicine storage case 900 and the main body 800 are connected in a watertight manner. That is, the tank connecting portion 914 is connected to the main body connecting portion 812 in a watertight manner. The tank seal member 906 is an example of an annular seal member disposed between the tank connection portion 914 and the body connection portion 812. The annular seal member may be disposed on the tank connecting portion 914 side or on the main body connecting portion 812 side.

As shown in fig. 18 and 19, the main body 800 includes an opening/closing valve 850. The opening and closing valve 850 has a valve seat 852 and a valve core 854. Valve seat 852 is conically concave. The valve core 854 has a valve sealing member 856 and a base 858. The valve seal member 856 is an annular seal member. The valve sealing member 856 is an O-ring. The valve sealing member 856 abuts the valve seat 852.

Fig. 22 (a) is a perspective view of the base 858 of the valve body 854, fig. 22 (b) is a plan view of the base 858, fig. 22 (c) is a side view of the base 858, and fig. 22 (d) is a bottom view of the base 858.

The valve body 854 (base 858) has: a valve body base portion 861, a valve body abutment portion 862, and a valve sliding portion 864, which are provided with a seal arrangement portion 860, are provided on the outer periphery.

The valve body base portion 861 constitutes a disk-shaped portion which is impermeable to water. The seal arrangement portion 860 is provided on the outer peripheral portion of the valve body base portion 861. The seal arrangement portion 860 is a groove along the circumferential direction. A valve seal member 856 is disposed in the seal disposition portion 860 (see fig. 18 and 19). The valve seal member 856 is an annular seal member. The valve sealing member 856 is an O-ring.

The valve body abutment 862 is formed of a convex portion protruding upward from the valve body base portion 861. The convex portion is formed in plural (three). The end surface of the projection abuts against the lower end surface 963 of the medicine storage case 900 (the lower end surface 963 of the case connection portion 914).

The valve slide portion 864 is a plate-shaped portion that protrudes downward. The valve slide portion 864 is slidably engaged with a slide guide portion described later, and the valve body 854 is movable.

Fig. 23 (a) is a perspective view of the valve abutment member 870, fig. 23 (b) is a top view of the valve abutment member 870, fig. 23 (c) is a front view of the valve abutment member 870, and fig. 23 (d) is a side view of the valve abutment member 870.

The valve abutment member 870 is a nut member that fixes the respective members constituting the main portion 803 of the main body portion 800 in an assembled state. In addition, the valve abutment member 870 has an inner flow path 872. The inner flow passage 872 communicates with the main flow passage 810.

The valve abutment member 870 has a slide guide 874. The slide guide 874 is formed of a slit portion opened at an upper side. The slit portions are provided at two locations in the circumferential direction of the valve abutment member 870. As shown in fig. 18 and 19, the valve sliding portion 864 is inserted into the sliding guide 874 from the upper side. The valve sliding portion 864 is slidably movable in the slide guide portion 874.

The slide guide 874 is slidably engaged with the valve slide 864, whereby the valve body 854 can reciprocate in the valve opening/closing direction. The valve opening/closing direction is the up-down direction.

When the valve body 854 moves in the valve closing direction, the valve seal member 856 abuts against the valve seat 852, and the opening/closing valve 850 is closed (see fig. 19). In the present embodiment, the valve closing direction is the upward direction. Due to the water pressure, the valve core 854 is biased in the valve closing direction. The opening/closing valve 850 is closed by the water pressure as long as the medicine storage tank 900 does not hinder the movement in the valve closing direction. Further, a biasing member may be provided to bias the valve body 854 in the valve closing direction.

When the medicine storing tank 900 is attached to the main body 800, the tank connecting portion 914 (tank projecting pipe portion 964) moves the valve body 854 in the valve opening direction against the biasing force due to the water pressure. In the present embodiment, the valve opening direction is the downward direction. The tank connection portion 914 depresses the valve spool 854. The lower end surface 963 abuts against the spool abutment portion 862 of the spool 854 to move the spool 854 in the valve opening direction. As a result, the valve seal member 856 is separated from the valve seat 852, and the opening/closing valve 850 is opened (see fig. 18). The medicine storage case 900 has a valve open/close portion 965, and when the medicine storage case 900 is attached to the main body 800, the valve open/close portion 965 abuts against the valve body 854 (the valve body abutment portion 862) to move the valve body 854 in the opening direction. The valve open abutment 965 is a lower end surface 963.

Thus, the opening/closing valve 850 opens and closes a flow path of the body 800 extending from the main flow path 810 toward the body connecting portion 812 (the flow hole 940). When the medicine storing tank 900 is attached to the main body 800, the tank projecting pipe portion 964 presses the valve body 854 of the opening/closing valve 850 to open the opening/closing valve 850. When the medicine housing case 900 is removed from the main body 800, the case protruding tube portion 964 releases the pressure on the valve body 854 and closes the opening/closing valve 850.

The medicine 700 can be used at any time by opening and closing the valve 850. For example, the shower head 30 can be used without installing the medicine housing case 900, and the medicine housing case 900 can be installed during this use. Further, the medicine storage case 900 can be attached to use the shower head 30, and the medicine storage case 900 can be taken out during the use. Even if the medicine storage case 900 is taken out during use of the shower head 30, the opening/closing valve 850 is closed, and therefore, water is not blown out from the main body connecting portion 812. Even if the medicine storage case 900 is inadvertently dropped, water is not blown out. Further, by removing the medicine storage case 900 during use in a shower, the life of the medicine 700 can be extended, and the medicine 700 does not run out. This open/close valve 850 can also be applied to the shower head 10 of the first embodiment and the shower head 20 of the second embodiment.

In the shower head 30, a first water flow that reaches the water outlet portion 8044 from the main flow path 810 through the medicine housing space 930 and a second water flow that reaches the water outlet portion 804 from the main flow path 810 without passing through the medicine housing space 930 are also formed. By thus branching the flow, the water output is ensured and the desired duration is achieved. The valve abutment member 870 and the valve spool 854 participate in the branching of the water flow. A part of the water passing through the inner flow path 872 flows into the branch flow path 830 by contacting the valve body base portion 861 of the valve body 854. The other part of the water passing through the inner flow path 872 passes through the opening/closing valve 850 and then flows toward the medicine storage space 930. When the on-off valve 850 is in the closed state, water does not pass through the on-off valve 850, and the water flow becomes the second water flow only. When the on-off valve 850 is in the open state, the first water flow is possible due to the opening of the on-off valve 850, and the first water flow and the second water flow are formed.

Examples of the material of the lid 204 of the medicine-containing case 200 include resin and metal. As the resin, a thermoplastic resin is preferable from the viewpoint of ease of molding and excellent productivity. The cover 204 is an external component exposed to the outside, and is preferably made of a material suitable for vapor deposition. From this viewpoint, acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS) is preferable among the thermoplastic resins.

Examples of the material of the case main body 202 of the medicine-housing case 200 include resin and metal. As the resin, a thermoplastic resin is preferable from the viewpoint of ease of molding and excellent productivity. The case main body 202 preferably has transparency from the viewpoint of allowing the remaining amount of the medicine to be visually checked from the outside. The tank main body 202 preferably has a strength capable of withstanding the impact during the fall. From these viewpoints, Polycarbonate (PC) is preferable as the thermoplastic resin.

The material of the tank sealing member 206 is preferably rubber. The number of times of attachment and detachment of the medicine housing case 200 is large, and a material having excellent wear resistance is preferable. From this viewpoint, among the rubbers, Nitrile Butadiene Rubber (NBR) is preferable.

Examples of the material of the main body projecting tube portion 150 include resin and metal. As the resin, a thermoplastic resin is preferable from the viewpoint of ease of molding and excellent productivity. From the viewpoint of fixability to the main body 100 and support of the medicine-housing case 200, POM (polyoxymethylene) is preferable as the thermoplastic resin.
